Twaddle, as my Cornish co-worker used to say.
If Faye is willing to accompany Retta and chat up this Dina Engel woman, good for her. I've looked into the situation and spoken with the FBI agent in charge. It isn't a dangerous assignment, since the woman's drug king/husband shows little interest in her new career and will remain in Detroit. The agent simply needs a couple of over-fifty women who fit in with Love-able Ladies (yes, they really do add the hyphen), and Lars suggested us. Retta certainly fits the profile of a Love-able Ladies groupie, and Faye will be her chaperone.
I don't think they can possibly get into any trouble.
